I'm not sure where he's from originally. I know he was born in the US and lived here until he was into his thirties or forties, then moved to Australia. He said in his book that it was a dream of his to live there, and soon after the September 11 experience, he packed up his family and moved there because he decided to follow all of his dreams.
He's an interesting guy. Well educated, intelligent, and seems to be honest about what he's doing. I've heard him interviewed on the radio, and the interview was riveting. I really felt like I could relate to him, and that he isn't in this entirely for himself. He seems to be genuine in wanting to help people find the key to losing their weight and setting themselves free.
